gun move

A moment later, a pump-action shotgun popped up from below the counter.
The close-range blast reverberated in the gut more than the ears.
In a way, the solid and invisible wall of sound was even more of a weapon than the metal balls rushing toward them at blinding speed. Uiharu and Saten screamed and fell back onto the floor.
In this case, that was the correct response.
Sakibasu Yuri was in more danger since she mostly just stood there. Her black kneesocked legs turned inward and she only cowered down a little.
And.
“Tch!!”
Separate from that, some bluish-white sparks flew through the air.
The scattershot should have flown straight toward them from less than a meter away, but it veered off course and instead shattered the cylindrical bottles of formaldehyde specimens behind them.
Judgment.
The mere mention of that name was enough to cause this.

The old man in a track suit and mask rose from his small chair and pulled the trigger again.
More and more gunshots rang out, but none of them hit. Now, did he realize what was happening? Mikoto was not actually using magnetism or the Lorentz force to manipulate the bullets tearing through the air. She was instead using an invisible hand to grab and move the sight on top of the pump-action shotgun itself.
